The source tells Us Weekly exclusively that Kris was hand in hand with boyfriend Corey Gamble during the party, noting that he “was right behind Kris everywhere she went.” Caitlyn, meanwhile, who has an estranged relationship with Kris, Kim, Kourtney and Khloé, attended the get-together with pal Sophia Hutchins.

“Kris got on the microphone at midnight and said 21 years ago one of the biggest blessings of her life was born,” the source tells Us. “Then she said how grateful and appreciative that Travis and Kylie brought Stormi into her world. When Stormi was mentioned in Kris’ speech everyone gave a big round of applause.”
